A multi-purpose syringe for extracting a body fluid, storing the fluid and being adapted to be employed as the test vial for centrifugation. The syringe includes a vial and at the forward end a nozzle which is threadedly connected for sealing purposes to a cap which has a spike extending into the passageway through which blood is drawn. A threaded end cover sealingly engages the rearward end of the vial and piston rod protrudes therethrough. The rod has at the forward end a piston head provided with a rearwardly extending sleeve which is placed into sealed locking engagement with the end cover after the specimen has been introduced or drawn into the vial. The combination of the cap at one end and the cover member at the other end provides a complete seal for the container. The piston rod has two portions which can be severed from each other.
